I think it's pure luck that that doesn't throw an error.
You should not be using the EXEC SQL prefix for something
that isn't a SQL command.
Anyway, the problem you're hitting here is that as soon as you
say EXEC SQL, the syntax rules for quoted strings change.
This is not well documented, and I think it's got some bugs
in itself [1], but "EXEC SQL char *bar = "aaa\"bbb";" is just
wrong. You can't use C literal syntax inside a SQL code
segment, whether or not the command would work otherwise.
